4 dogs killed as officers rescue Arizona boy being mauled

Sierra Vista police say several dogs bit and seriously injured a 9-year-old boy in the yard of the home where the dogs and the boy lived and that responding officers fatally shot three dogs to rescue the child.

According to police, a fourth dog was fatally shot when it appeared to charge an officer during the Wednesday incident.

Police Sgt. Brian Sebastian said the boy was expected to recover from his injuries.

A police statement said a passerby called 911 to report seeing dogs biting the boy inside the fenced yard.

The statement said an officer tried using a stun gun to try to drive the dogs away from the injured boy but that three dogs were shot because they remained near the boy who couldn't reach a gate.
